I suggest to add Kconfig dependency b/w SPI_FLASH_MTD and MTD. Something like:

It is necessary to call spi_claim_bus() before starting any SPI
transactions and this restriction would also apply when calling spi-mem
operationss. Therefore claim and release bus before requesting transfer
via exec_op.
